A: When it comes to transformer oil, we may hear the most oil-immersed transformer oil, as for dry-type transformer oil basically never heard of. We all know that the most important role of oil-immersed transformer oil is to be used to reduce the temperature, then in the end what is the use of dry-type transformer oil, does anyone know?

The role of dry-type transformer oil is still more obvious, the role is also more. Dry-type transformer oil is also enlightened to the role of heat dissipation, but the role of oil-immersed transformer oil is not as big as the role of heat dissipation, often used as a refrigerant, through convection to absorb the heat of the transformer, to ensure the normal operation of the dry-type transformer; At the same time, dry-type transformer oil also has the role of insulation. Transformer oil insulation strength is not only higher than the insulation strength of the air, at the same time can isolate the air and transformer parts and components contact, to avoid corrosion; Finally, transformer oil also has the role of arc extinguishing, transformer thermal conductivity is relatively good, and at the same time in the high temperature will be released under the action of the otherwise gas, thus improving the arc extinguishing performance, is the arc will soon be extinguished.
